The underwater FRP pile jackes reinforcement system, also known as the "jacket method", is a reinforcement technology used for the reinforcement, repair, and protection of underwater pile foundations and pier columns. It mainly consists of underwater epoxy grouting material and customized FRP pile jackes, and can complete the repair and reinforcement of bridge piles made of various materials such as concrete piles, steel piles, and wooden piles under underwater operation.

Application scope

1. Reinforcement of various corroded structural foundations and dock pile foundations

2. Repair and reinforcement of bridge pier columns (including concrete piles, steel piles, and wooden piles)

3. Pre protection for newly established institutions

Product features

Corrosion resistance - using Hydro polymer, it has a high-strength anti-corrosion effect and can withstand seawater corrosion. Due to the inertness of glass fiber sleeves to chemical reactions, they can resist various chemical agents and have acid and alkali resistance.

Underwater construction - due to its insensitivity to water, it still has super strong and tight adhesion during underwater construction. Especially, underwater construction can be carried out without the need for building cofferdams and expensive drainage equipment. It is the best anti-corrosion system that saves time, labor, and money.

Durability - It can resist the interaction of dry and wet, cold and hot, freeze-thaw, and continuous or intermittent corrosion caused by climate cycles, as well as water flow, ocean tides, wastewater, electrolysis, etc., with excellent durability.

Product comparison

• Traditional restoration: Using the same materials (wood, concrete, steel) used in the original building to complete the restoration work

• Unable to fundamentally improve the corrosion resistance of the structure

• Short maintenance cycle (requiring multiple repairs in the future)

• Good anti-corrosion performance, preventing future structural damage
  

• One-time investment, free of long-term maintenance
